ABSTRACT


Purpose: Assessment Of The Influence Of Attachment Types And Standard Inter-implant Distance On Retention Of Mandibular Implant Overdentures

Materials and Methods: Twelve Fully Edentulous Patients Were Enrolled For This Study. Conventional Complete Dentures Were Made And Duplicated Into Stereolithographic Surgical Guide Using CBCT. According To Implant Planning, Each Patient Received Two Anterior Mandibular Implants Placed At The Anterior Region Bilaterally With Inter Implant-distance 19 Mm . After 3-4 Months Osseointegration Period, OTEquator Attachments Were Screwed To The Implants For Group A And Locator Attachment Were Screwed To Implants For Group B, And Matrices Were Picked-up Into The Mandibular Overdenture. The Retention Of The Mandibular Overdenture Was Evaluated Before Insertion (T0),at Time Of Insertion Of Mandibular Over-denture (T1), Three Months After Insertion (T3

Results: Comparing The Retentive Forces Of The Prosthesis At Different Periods Of Study, There Was Statistically Significant Decrease In Retention Measurements Before Over Denture Insertion, Significant Increase In Retention At Time Of Insertion Of Overdenture Also A Significant Increase Of Retention After 3 Months From Denture Insertion Was Observed Conclusion: Two Implant Overdenture With OTEquator And Locator Attachments Could Be A Reliable Treatment Option For Edentulous Mandible In This Short Term Study .
